A History of suction-Type Laminar-Flow control
In that study, the flow characteristics and flow distribution patterns of a single slot jet as well as a multiple slot jet located at the upper wall of a two-dimensional channel were analyzed numerically. The pressure distribution of the channel and the variation in skin friction coefficients along the impingement surface plate were also presented.
Polymer/riblet combination for hydrodynamic skin friction ... Reducing this drag component would have the obvious advantages of increased speed and/or efficiency. One approach to skin friction drag reduction involves the use of long chain polymer molecules, which can reduce up to 80% of the skin friction under ideal circumstances. Friction of Human Skin against Different Fabrics for Medical Use friction in a reciprocating test [17]. Deformation of the skin and/or high coefficients of friction during skin product interactions could cause discomfort, since the subsurface stress and strains within the skin are influenced by skin friction, and according to Xu et al. [18], a threshold exists for Effect of Jet Oscillation on the Maximum Impingement Plate ... Both of these jet oscillation features result in a reduction in the time-averaged maximum impingement plate skin friction. This skin friction reduction is attributed to momentum loss at the jet centerline caused by increased levels of fluid entrainment and mixing of the surrounding quiescent fluid. Direct measurement and analysis of skin friction and cooling ...

Skin friction reduction in supersonic flow by injection through slots… An experimental study of skin friction reduction in a Mach 3.0 air steam with gaseous injection through a tangential slot, a porous wall section, and combinations of the two was conducted. The primary data obtained were wall shear values measured directly with a floating element balance and also inferred from Preston Tube measurements.
